Knowledgeblog ArrayExpress Plugin

Using the [aexp][/aexp] shortcode, metadata can be extracted for a number of components for an ArrayExpress entry. Descriptions, citations, links to raw files etc. can all be inserted into a WordPress post.

Currently the following attributes are supported for shortcodes of the format [aexp id=”E-MEXP-NNNN”]metadata_type[/aexp]

The following is a short demonstration of the metadata returned for these types for experiment [aexp id=”E-MEXP-1557″]accession[/aexp] in ArrayExpress. This link to the dataset page is generated by the “accession” shortcode in the previous sentence.

The short title of the experiment is “[aexp id=”E-MEXP-1557″]name[/aexp]” and the experiment used [aexp id=”E-MEXP-1557″]species[/aexp]. It was submitted on [aexp id=”E-MEXP-1557″]submissiondate[/aexp], released on [aexp id=”E-MEXP-1557″]releasedate[/aexp] and last updated on [aexp id=”E-MEXP-1557″]lastupdate[/aexp].

ArrayExpress categorises the experiment with a MIAME [aexp id=”E-MEXP-1557″]score[/aexp]. The contact for the experiment is [aexp id=”E-MEXP-1557″]contact[/aexp].

This experiment has no publication associated with it but has the following citation information: “[aexp id=”E-MEXP-1557″]citation[/aexp]”.

To show an example dataset with a citation here is the same information for [aexp id=”E-MEXP-1551″]accession[/aexp]: “[aexp id=”E-MEXP-1551″]citation[/aexp]”

In [aexp id=”E-MEXP-1557″]accession[/aexp] there are [aexp id=”E-MEXP-1557″]samples[/aexp] samples and [aexp id=”E-MEXP-1551″]assays[/aexp] assays. The array design used is [aexp id=”E-MEXP-1557″]arraydesign[/aexp]

These are the links to the dataset files: [aexp id=”E-MEXP-1557″]datafiles[/aexp]

It is possible to interrogate the types of experiment: [aexp id=”E-MEXP-1557″]experimenttypes[/aexp]

It is possible also to retrieve the factors of the experiment: [aexp id=”E-MEXP-1557″]experimentalfactors[/aexp]

And we can pull out information about the sample attributes: [aexp id=”E-MEXP-1557″]sampleattributes[/aexp]

Finally it is possible to link to png and svg versions showing the origin of the biosamples in the experiment:
